Check Digit Verification of cas no

The CAS Registry Mumber 133531-68-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,3 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 133531-68:
(8*1)+(7*3)+(6*3)+(5*5)+(4*3)+(3*1)+(2*6)+(1*8)=107
107 % 10 = 7
So 133531-68-7 is a valid CAS Registry Number.

Synthesis and toxicity of new ring-fused imidazo[5,4-f] benzimidazolequinones and mechanism using amine N-oxide cyclizations

Fagan, Vincent,Bonham, Sarah,McArdle, Patrick,Carty, Michael P.,Aldabbagh, Fawaz

experimental part, p. 1967 - 1975 (2012/05/31)

A new synthetic route to ring-fused imidazo[5,4-f]benzimidazoles is reported that can be used to access symmetrical and unsymmetrical quinone anticancer agents. Oxone in formic acid allows cyclisation of o-tert-aminoacetanilides to give ring-fused benzimi
